DarkPlaces is a game engine based on the Quake 1 engine by id Software. It improves and builds upon the original 1996 engine by adding modern rendering features, and expanding upon the engine's native game code language QuakeC, as well as supporting additional map and model formats.
Developed by LadyHavoc. See CREDITS for a list of contributors.

Linux x86_64 builds are available in GitHub CI artifacts.
More complete builds are available in xonotic.org engine zips.
These support Windows, Linux and macOS, and include the current libraries needed for all features.
DarkPlaces supports many Quake-based games and you can select which it will run by renaming the executable so it's prefixed with the game's name, for example rogue-sdl.exe, or by passing a cmdline argument
such as -rogue. This changes various engine behaviours and cvar defaults to suit the game.
The supported list and related details are defined in com_game.c.
Mods which aren't listed there can be run with (for example) -game quake15 in which case DP will use the same behaviours and cvar defaults as for id1 Quake.
All of Quake's data access is through a hierarchical file system, the contents of the file system can be transparently merged from several sources.
The "base directory" is the path to the directory holding the quake.exe and all game directories. This can be overridden with the "-basedir" command line parm to allow code debugging in a different directory. The base directory is only used during filesystem initialization.
The "game directory" is the first tree on the search path and directory that all generated files (savegames, screenshots, demos, config files) will be saved to. This can be overridden with the "-game" command line parameter. If multiple "-game " args are passed the last one is the "primary" and files will be saved there, the rest are read-only.
These instructions are adequate for Quake, but for Xonotic please refer to its wiki.
The minimum SDL version is 2.0.18 for Linux and 2.24.0 for Windows.
The supported compilers are GCC and Clang.
The following package names are for Debian, see below for Windows and Mac.
Build (mandatory): build-essential libjpeg-dev libsdl2-dev
Runtime (optional): libcurl libpng libfreetype6 libvorbisfile
Build (mandatory): build-essential libjpeg-dev zlib1g-dev
Runtime (optional): libcurl libpng
- Install MSYS2, found here.
- Once you've installed MSYS2 and have fully updated it, open a MinGW64 terminal (not an MSYS2 terminal) and input the following command:
pacman -S --needed gcc make mingw-w64-x86_64-{toolchain,libjpeg-turbo,libpng,libogg,libvorbis,SDL2}
- See Unix instructions.
- Open a terminal and input
xcode-select --install - Install Homebrew
- In the same (or a different terminal), input the following command:
brew install sdl2 libjpeg-turbo libpng libvorbis curl
- See Unix instructions.
From a terminal, in the engine's root directory, input make help to list the targets.
To build the main executable, input make sdl-release which creates the file called
darkplaces-sdl or darkplaces-sdl.exe (Windows).
If you get errors (that don't seem to be about missing dependencies) try make clean before compiling, especially if you updated your system since the last time you compiled.
Not recommended due to poor support for C standards, and lack of maintenance.
DarkPlaces requires C11, so Windows SDK 10.0.20348.0 or later is needed.
To install it, run the Visual Studio Installer, click "Modify", click "Individual components", type "Windows SDK" in the search box, select the latest Windows SDK and de-select older versions.
You will also need "NuGet package manager" selected (to download SDL2 headers the first time you build).
Click "Modify" to apply the changes.
Open darkplaces-vs2019.sln, select build type (Debug or Release) and platform (Win32 or x64), and choose "Build Solution" from the "Build" menu to create files darkplaces-sdl2-vs2019.exe and SDL2.dll.
The Release build crashes. The Debug x64 build doesn't crash (but is rather slow) so this will be Fun for someone to debug.
To get a build suitable for playing you'll need to use MinGW GCC, or download the autobuild from Xonotic (see above).
Note that this requires a linux device or WSL2.
- Install the Emscripten SDK
- After activating and sourcing emsdk, compile DarkPlaces for wasm using;
make emscripten-release
- Copy
darkplaces-wasm.js,wasm/index.html, andwasm/autoexec.cfgfiles to your web server - Copy the Quake
pak0.pakand any other files into the same web server directory
For the standalone version (single HTML file containing engine and data):
- Before compiling, copy game data and .cfg files to the appropriate gamedir in
wasm/preload(for example, pak0 from Quake would be inwasm/preload/id1/pak0.pak) - After activating and sourcing emsdk, compile DarkPlaces for wasm using;
make emscripten-standalone
- To start DP you must click somewhere in the window!
- If you want to upload files into the game filesystem, use
em_uploadin the darkplaces console (upload to /save if you want it to save across restarts) - To save the stuff you uploaded to /save, use
em_save(note that if you embedded the game, you won't be able to save changes to/save/games)
